Data collection in QI work is critical to understanding the impact of your Change Ideas on your system. In quality improvement work, three types of measures are used to measure and understand your improvements; Outcome Measures, Balancing Measures and Process Measures. Collectively, these measures are known as the ‘Family of Measures.’ This resource provides a description of each of these measures as well as worksheets you can use to develop and record measures for your own QI project.
